martinf Posted June 3, 2017 Share Posted June 3, 2017 Having problems getting my spring brake cans aired up on my mid seventies R. I was going to put the bolt in and lock them so I could move it over to my shop (100 ft)...those bolts are missing on both cans! They're usually in that little holder on the can itself right? Anyways I've seen these things plenty of times, but I can't quite picture them enough to make them. How bout all thread with a pin welded across the top? Or is there a place I can buy them cheap and quick? Thanks for any advice.

Timmyb Posted June 3, 2017 Share Posted June 3, 2017 You should be able to rob some off any other brake chamber to get you going. Just be sure to put them back. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/50053-spring-brakes/#findComment-371349 Share on other sites More sharing options...
martinf Posted June 4, 2017 Author Share Posted June 4, 2017 Thanks for the suggestions guys. For some reason I have no air coming back to the spring brakes...and when I press in the treadle, the a huge gush of air coming out of the treadle valve. This girl ran ok when I parked her 6 years ago. I don't have the time right now to problem solve...just neede to move her. So that's why I'll just do the caging bolts quick. If you have any ideas about the bigger issue tho, I'm all ears. thanks martin Quote 1965 Mack B-74, dump1974 Mack R, logging w/Prentice self-loaderwww.somewhereonthemountain.blogspot.com Link to comment https://www.bigmacktrucks.com/topic/50053-spring-brakes/#findComment-371400 Share on other sites More sharing options...
